Inside Enclosure Maintenance
Checking Battery
Battery status should be checked every 3 months. This is done either
using a multi-meter on the batteries' plus and minus ends, or by pressing
the QBR101 battery charger. Press the QBR101C battery charger status
button to see the battery status and if the system has any power
(AC(mains)/battery):
- If the LED is green, the battery is OK.
- If the LED is yellow, the battery voltage is low (charge <11.5 V).
- If the LED is red, the battery is empty (charge <10 V).
If the battery status is red even after charging for a while, the battery is
old and needs to be replaced. The lead acid battery may age in 3 to
5 years and needs to be replaced with a new one.
Pressure Sensor BARO-1
Periodic Maintenance
Under normal operating conditions, BARO-1 needs only a minimal
amount of maintenance.
- Keep the pressure port clean. Check the pressure port every time when
visiting the site.
- Annually, compare pressure values against a calibrated portable
standard.
